摘　　要：82 000 DWT散货船舷侧为单壳横骨架式结构。舷侧肋骨上下两端用肘板与底边舱和顶边舱相连接,易产生应力集中,是整个散货船船体结构中比较关键的区域之一。端部肘板需通过有限元计算才能最终确定。舷侧肋骨端部肘板设计遵守《散货船油船协调共同规范》(HCSR)要求,在计算得到肘板臂长、净剖面模数和净厚度等规范尺寸的基础上,应用有限元法将端部肘板区域网格细化。计算分析不同肘板趾端标准节点型式和构件大小情况下肘板端部出现的最大应力。在满足规范许用应力前提下选取肘板最优设计方案。The side of the 82 000 DWT bulk carrier is a single hull transversely framed structure.The side frames are connected with the hopper tank and topside tank by end brackets,which is one of the key areas of the whole hull structures of bulk carriers,where the stress concentration might occur.The end brackets are finally determined through finite element calculation.The design of the brackets at the ends of the side frame shall follow the requirements of common structural rules for bulk carriers and oil tankers(HCSR).Based on the calculation of the arm length,net section modulus and net thickness of the bracket,the finite element method was applied to refine the mesh of the end bracket area.The fine mesh analysis was carried out to compare the max stress at the end of bracket under different standard types of the brackets toe and component sizes.The optimal design scheme of the bracket was selected under the premise of meeting the allowable stress in the rules.
